The left anterior descending artery (arrow) is embedded through all of its length in the epicardial fat. *Interventricular septum. CCTA coronary computed tomographic angiography.;Coronary morphology;The normal LAD;Intramuscula LAD, superficial type, as seen on axial plane (A, B) and multiplanar reformation (C, D). The mid LAD (arrow) shows a typical deviation and straitening and is only partially surrounded by myocardium. Of note, an atheroscleroticplaque in the proximal LAD, whereas the intramuscular segment is free of disease. ;Intramuscular LAD, righ
